	Measure accuracy: 1% (± 1 digit)
	Operating temperature: -10 to 65° c
	Operating Humidity: 10 to 80% (non-condensing)
	Working pressure: 80 to 106 kPa
	Applications:Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement
	 
	Wiring:
	 
	Black line (thin): vacant or buck circuit (module) negative
	Red line (thin): power supply+
	Black line (thick): COM, common measuring
	Red line (thick): PW+, measuring terminal voltage input positive
	Yellow line (thick): IN+, current input+
	 
	Notice:
	 
	The voltage between the thin red and thin black lines must be within DC 4-30V
	The ammeter can only be connected to the negative of the device under test
	Exceeds 5A, long-term full load working continuously, it is recommended that the measurement side of the leads are directly soldered to the socket
	When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
	If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
	It is unsuitable to use this meter to test current less than 10A .
